Journal Article
Wu, Y. I., Lau, S. K., Wong, K. T., & Tang, S. K. (2010). Beacon-aided adaptive localization of noise sources aboard a pass-by railcar using a trackside microphone array. IEEE Transactions on Vehicular Technology, 59(8), 3720-3727. https://doi.org/10.1109/TVT.2010.2059056

A new adaptive "beamforming" signal-processing algorithm is developed to locate the loudest noise sources aboard a railcar that passes by a trackside immobile microphone array. This proposed microphone-array beamformer tracks the railcar's spatial mo...

Can surrounding greenery reduce noise annoyance at home? (2010)
Journal Article
Li, H. N., Chau, C. K., & Tang, S. K. (2010). Can surrounding greenery reduce noise annoyance at home?. The Science of the total environment, 408(20), 4376-4384. https://doi.org/10.1016/j.scitotenv.2010.06.025

Annoyance has been identified as the most important psychological impact arisen from noise. Besides socioeconomic status, residing neighborhood characteristics such as greenery has been shown to be able to reduce noise annoyance. To study the effects...

Scale model study of balcony insertion losses on a building façade with non-parallel line sources (2010)
Journal Article
Tang, S. K. (2010). Scale model study of balcony insertion losses on a building façade with non-parallel line sources. Applied acoustics. Acoustique appliqué. Angewandte Akustik, 71(10), 947-954. https://doi.org/10.1016/j.apacoust.2010.06.006

The screening effect of balconies on a building faade in the case where the noise source is not parallel to the faade is studied using scale model experiment in the present study. Results show that the angle of source inclination to the faade has sub... Read More about Scale model study of balcony insertion losses on a building façade with non-parallel line sources.

On sound transmission loss across a Helmholtz resonator in a low Mach number flow duct (2010)
Journal Article
Tang, S. K. (2010). On sound transmission loss across a Helmholtz resonator in a low Mach number flow duct. The Journal of the Acoustical Society of America, 127(6), 3519-3525. https://doi.org/10.1121/1.3409481

A simplified physical model, which described the generation of sound by a Helmholtz resonator upon flow excitation at its neck, was developed in the present investigation to study the drop in sound power transmission loss across such a resonator moun...
